I switched over to Vonage a couple months ago...very pleased with the service so far. And the fact that it's well less than half what I was paying the telco is great
I did hook it up so that all my jacks in my house are connected. Had to disconnect the main phone box from the telco (they're very specific to do so or you 'could' end up frying the vonage equipment). Then, backfeed the vonage box into any phone jack and the rest of the house is live...very cool
I've had no dropped calls or poor quality here. Only thing I noticed is that the sound is louder on my cordless phone, so I turned it down a notch and all is good
